cozy winter sleep without the worry
When the temperature drops, keep baby's sleep perfectly warm with our premium winter sleep bags. Designed specifically for cooler environments, these warm sleep sacks combine plush insulation with the breathable comfort of bamboo rayon—creating the ideal microclimate for deeper, longer winter sleep.
The generous cut allows for natural movement and healthy hip development, while still fitting snugly at the arms and neck to prevent cold drafts. Our innovative WONDERZiP® means those inevitable midnight diaper changes happen quickly, without fully exposing baby to chilly air or disrupting their cozy sleep environment. It's thoughtful winter comfort, wrapped in the silkiest package.
